DESCRIPTION
TOA's TC-651M Reflex Horn Speaker, rated at 50W, are designed for outdoor paging applications in houses of worship, factories,
schools and so on.
The speaker features newly developed diaphragms employing special heat-resistant polyimide film to prevent the diaphragm from
absorbing moisture and changing shape, as well as to improve the low frequency characteristics. TC-651M has been proved to
provide more than 100 hours of operation at 50 W in continuous load test employing test signal that meets the International
Electrotechnical Commission (IEC). High speaker efficiency has also been realized by minimizing the gap produced when the
diaphragm bobbin is installed in the magnetic circuitry slit.
TC-651M is designed to ensure high speech clarity and sound quality suitable for music reproduction.
External hardware (screws, bolts, nuts) are made of stainless steel, and the mounting bracket and the horn itself are treated with 50micron thick powder paint coating. All of these factors combine to ensure the speaker's excellent weatherproofing and corrosion
resistance. In addition, the external horn flare is made of aluminum that is more shock-resistant than resin.
TC-651M is equipped with an input impedance selector switch (3 steps for 100V line, and 4 steps for 70V line) which facilitates the
ease of impedance settings without requiring disassembly. The switch is also equipped with an OFF position to prevent speaker
damage resulting from incorrect impedance setting.
FEATURES
• Compact and high power horn speaker.
• High durability, high heat-resistance and improved low frequency sound thanks to polyimide
diaphragm.
• More than 100 hours of operation at 50 W in continuous load test employing test signal that
meets IEC 60268-1: 1985 standard.
• Stainless steel hardware (screws, bolts, nuts), and powder-coated horn and bracket for
weatherproofing and corrosion-resistance.
• Shock-resistant aluminum round horn.
• Compliance with IP65.
• Easy impedance matching with panel-mounted input impedance selector.
• Wide temperature range: -20°C to 60°C (-4°F to 140°F).

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The specified horn speaker shall be designed especially for outdoor
applications. The horn speaker shall be a reflex horn type suitable for paging and
tone signaling distribution. The speaker component shall be a compression
driver with a polyimide diaphragm to prevent deformation from heat and improve
low frequency characteristics.
